The abrt-action-install-debuginfo-to-abrt-cache help program in Automatic Bug Reporting Tool (ABRT) before 2.7.1 allows local users to write to arbitrary files via a symlink attack on unpacked.cpio in a pre-created directory with a predictable name in /var/tmp.

The information has been provided by The vendor reported this issue.

abrt is prone to a security vulnerability because it creates temporary files in an insecure manner. An attacker with local access could potentially exploit this issue to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.
